Welcome to RD Sips,

made in Herefordshire and delivered across the UK

RD SIPs supplies certified structural insulated panels (SIPs) and SIP kits for extensions, annexes, garden rooms and houses across the UK. We’re based in Herefordshire and built the business to make SIPs accessible for smaller jobs—without the long lead times, high costs, or lack of support you often get elsewhere.

From first drawings to delivery, we keep it simple: clear advice, fast turnaround where possible, and quality-controlled panels made to meet UK building regs—so you can build quicker, warmer, and with less hassle.

What comes in our standard kits:

Floor SIP panels (if the design uses a SIP floor) cut to plan
External wall SIP panels cut to elevations (incl. corners and junction details)
Roof SIP panels (flat or pitched, depending on design)
Openings pre-formed / set out for things like doors, windows, and (commonly) bifolds on extensions
Connection/joining components (e.g., splines/junction timbers as required by the panel system/design)
A panel layout / install pack (drawings that show what each panel is, where it goes, and the build sequence)
Technical guidance/support (how to handle, dry-fit, fix, foam/glue, and weather-proof during install)
